Numerical Modeling Research About Putaohua Ⅰ1-2 Layer In The South West Lamadian Oil Field

The oil development has been in the high water development stage. Polymer flooding is an important technique to improve recovery factor in the oil field, and the technique of numerical modeling is an important technique guarantee to meliorate the effect of development of the field. The Putaohuaâ… 1-2 reservoir was infused polymer at July 2004, in the south west lamadian oil field. At the initial stages of making the block development plan of the polymer, the research of numerical modeling is basis on the numerical model of water driving stage, by macroscopical view, simulate the dynamic change characteristic and exploitation effect of the polymer flooding block at the same polymer concentration and under different infusing mode, it can't simulate every provision finely (for example: adjust perfectly absorption profile, series block off, break down, perforations adding, adjusting speed, water driving well stay so on ), leading infection of exploitation effect about the integrated adjust eg. the work system of single well. So there is a few difference between the result of polymer numerical modeling and local practice effect. For posting more personality and truly the movement rule of water and oil underground and describing finely the distributing condition of surplus oil after the water and polymer driving. For optimizing the integrated adjust project of polymer flooding and making actually measure project of single well to offer basis, for advance the efficiency of integrated adjust project, for improve the effect of polymer developing continually, it is very important for theory and local application to develop the numerical modeling research of the Putaohuaâ… 1-2 reservoir of Lamadian oil field.Throw the item research, making a suit of numerical modeling technique of the polymer flooding about local practice in the oil field, and confirming the measure of advancing polymer project and choosing the parameter of injection and projection, it has practice value in the local application of the polymer flooding tracking, it offer the guidance and reference for the other block and oil layer of adjusting of polymer flooding tracking.
